Home / Population and society / Articles / Six years after the Supreme Court ruling, what's the state of same-sex marriage in the US?

The 2020 Census asks cohabitating couples to define their relationship in a new way: "same-sex" or "opposite-sex.”

The question is the first time in the Census Bureau’s history was asked in its decennial survey of every household in America.

The Census is delaying the release of the detailed tables from the 2020 Census due in part to the difficulties posed by the COVID-19 pandemic on data collection. In the meantime, data from the Census’ 2019 American Community Survey (ACS) not only estimates the number of same-sex couples, but also provides a demographic and geographic understanding of such relationships.

The annual survey offers a glimpse into gay and lesbian couples in America, but the data is limited. Currently, the Census does not tabulate measures of alternative arrangements—such as civil unions or domestic partnerships—and the measurements of the marriage status of same-sex couples have been found by some Census research to be imperfect.

What percent of same-sex couples are married?

The Supreme Court ruled in 2015 that the fundamental right to marry is guaranteed to same-sex couples. At the time, the number of same-sex married couples and same-sex unmarried partner couples were about equal: 425,357 married and 433,539 unmarried. Since 2015, the number of same-sex married couples has risen while the number of same-sex unmarried couples has mostly declined.

In 2019, there were a total of 980,276 same-sex couples. Of these, about 47% (462,215) were male-male while about 53% (518,061) were female-female.

Of the 568,110 same-sex married couples in the US, about 47% (264,691) were male only and about 53% (303,419) female only.

For the 412,166 same-sex unmarried partner couples, about 48% (197,524) were male only. About 52% (214,642) were female only.
